2、Can storms in Africa cause asthma(哮喘) in the Caribbean(加勒比)? Islanders point to the desert insects that land on beaches after a 5,000-kilometer flight across the Atlantic. If they can use winds to get from one continent to another, so can clouds of dust that carry disease.

Scientists think that as Africa becomes drier, dust from expanding deserts is being blown away into Caribbean islands. A study in Barbados shows that asthma has increased 17 times since Africa’s drought(干旱) began in 1973.

Other forms of life are suffering, too. Among them are the Caribbean’s famous coral reefs( 珊瑚礁), which began dying in large numbers in the 1900s. Eugene Shinn of the U.S. Geiological Sudrvey(USGS) in Florida went to the virgin Islands to study the reefs. The tests he and his colleagues carried out showed that the coral was dying of disease caused by Africa microbes(微生物) from across the ocean.

William Sprigg of the University of Arizona is studying the problem as part of a major UN project. He says that dust is causing problems in the U.S., too.

“We are just beginning to collect the evidence of airborne(空气传播的) dust influences on human health,” he told The Washington Post.

1、Diamonds may be forever. But what’s a girl to do when she gets dumped (失恋) or divorced (离婚) and those rings, necklace and love gifts lose their emotional (情感) sense?

Help is just a click away on new Web sites that provide an outlet for selling jewelry(珠宝) from past relationships, sharing break-up stories and helping broken hearts heal (愈合).

“You go through a divorce. What do you do with that ring? Maybe you have a child you can pass it on to. Maybe you don’t. It just sits there, ” said Megahn Perry, who with her stepmother (继母) Marie Perry runs www.exboyfriendjewelry.com.

Three months after its start with the slogan(口号) “You Don’t Want It. He Can’t Have It Back,” the web site has 3,000 registered users and more than 600 postings of rings, bracelets and earrings for sale―all with a personal tale attached.

As one woman posting a diamond ring for $3,500 wrote:

“Beautiful ring came with a wrong man. Decided to sell to regain the money that I spent finishing payments on the ring that my ex didn’t.”

The idea was born when Megahn Perry, a Los Angeles actress and writer, was looking for a safe place to sell a wedding set after a divorce and realized others might have former boyfriends’ jewelry with memories(记忆) that make them too painful to wear.

The local pawn shop(当铺) proved an unattractive choice. So she teamed up with her stepmother Marie, researched the market and found a gap in it.
